Cutting-edge leak detection in an ancient city

Feature
Jerusalem is one of the oldest cities in the world, its origins dating back to the fourth millennium BC. It is a city covered with history – monuments and buildings reflecting its colourful past. At the same time, it is dynamic, modern and growing rapidly, placing huges train on an infrastructure which relies on components that are up to 85 years old. Since 1996 the Hagihon Company has been... [read more]

Optimising flow control in the digital age

Feature
The Industrial Internet of Things (IIOT) has been heralded as a great enabler that will revolutionise manufacturing and processing. Although asset-heavy industries were slow on the initial uptake, as the cost of sensor and network development declines it is becoming more feasible to outfit industrial equipment with devices to capture and communicate data. An emerging era of smart industrial... [read more]

Harnessing the energy of the sea

Feature
Developing new sustainable, ecologically acceptable technologies for heating and cooling domestic and commercial premises has been challenging the resources of many energy companies around the world. Harnessing the potential of the sun, sea tides and currents, the wind and the heat trapped deep beneath the earth’s surface have all proven to be successful technologies to varying degrees. To...

Proper pump selection for wastewater treatment plant pumps

Feature
Access to clean water is essential to sustain and provide for the continued development of the world’s population and its economic growth. Even though approximately two thirds of the earth’s surface is covered by water most cannot be used for drinking without treatment. Therefore, treatment plants are integral to solving one of the most urgent concerns today, to have sufficient... [read more]

Choose your mixers - stainless steel versus fibreglass

Feature
At one of the largest research parks in the world, there is no shortage of expertise in weighing up whether one material is more suitable than another. With more than 200 companies and over 50,000 people skilled in fields such as micro-electronics, telecommunications, biotechnology, chemicals, pharmaceuticals and environmental services; Research TrianglePark in Durham County, North Carolina is a...

Neither too much nor too little

Feature
Many wastewater and clean water processes require mixing and agitation to enhance the reaction time and to optimise the process. In addition, there can be several other demands that must be considered to ensure a well-functioning process. Selecting and designing agitators for water and wastewater applications is very much about finding the right balance – there should be neither too much... [read more]

Designing the 'world's biggest' water gate valve

Feature
“Everything is big in Texas”, the saying goes, and that is definitely true of its water demand. Texas is the second largest state in the US both in terms of area and population. Its huge expanse includes a range of different climates, from arid to humid, yet it is always hot, making a reliable water supply vital. In Texas lies Dallas – Fort Worth Metroplex (DFW) province, the... [read more]

Keeping the flow

Feature
Flow is very simply defined as a volume of a material travelling within a given time, so cubic metres per hour or litres per second etc. There are a variety of ways that we can directly and indirectly monitor flow and flow rate, one of which is to measure the velocity of flow and relate it to an area. Inclosed pipes, magnetic flowmeters work on this principle, measuring changes in magnetic flux... [read more]

Winds of change

Feature
Across the world there are tens of thousands of sewage treatment plants treating billions of litres of sewage everyday. Myriad measuring instruments monitor and measure water or sewage for level, flow, pressure, and water quality, as well as controlling increasingly complex biological processes at the treatment facilities themselves. Level is one of the most common measurements– for example... [read more]

Chemical control in wastewater

Feature
It is well documented that the appropriate control of nutrients such as phosphorous in the world’s water courses is vital for a cleaner, sustainable future. With this in mind, the European Water Framework Directive (Directive 2000/60/EC) has set an ambitious goal, demanding that rivers, lakes, coastal waters and groundwater be in a “good ecological and chemical condition” by...

Water leak detection from up high

Feature
In some places in Europe, as much as 50% of water resources are being lost before they reach the tap. The WADI project aims to address the challenge of building a water and energy efficient society by contributing to the reduction of losses in water transmission systems for water supply, irrigation and hydropower while decreasing the related energy consumption. The project aims to prove the... [read more]

Website Exclusive: Intelligent wastewater pumping

Feature
As the wastewater sector continues to focus on driving energy efficiency and a reduction in the total cost of pump ownership, the demand for intelligent, sustainable pumping solutions has never been greater. Global water technology company Xylem is committed to advancing technological breakthroughs that can solve customers’ greatest needs, while reducing electricity related emissions.... [read more]

Website Exclusive: A fundamental breakthrough

Feature
There are many ultrasonic choices that are used for level monitorinig in the universe of sewers, pipes and storm-water control. Although many circumstances in this environment, such as turbulence and unwanted obstructions, pose a challenge for most ultrasonics used in the fluid handling industry, they present no problem for the MassaSonic FlatPack. The broad beamed duel transducer system is... [read more]

Website Exclusive: A single source for wastewater handling technology

Feature
Applications for material handling and pumping technology in the wastewater industry tend to be complex, with a number of different people and organisations involved in installation and operation. The need to coordinate among officials from one or several municipalities, contractors and engineers means that designing, installing and operating material handling technology within these contexts is...

Website Exclusive: The power of flood prevention

Feature
The Colombian State of Antioquia creates much of its clean power from hydro plants along the Guadalupe River. In the case of the Guadalupe IV hydroelectric plant, the risk of flooding required a suitable solution to ensure that the ejector pumps would work regardless of power or pressure differentials. Three vertical axis turbines that discharge water below the river levelgenerate power for the... [read more]
